MyanTyper
Private, guided practice for the Windows Myanmar Visual-order keyboard
A free, open-source touch-typing tutor for the Windows Myanmar (Visual order) keyboard. It teaches finger placement, Shift combinations, and multi-code-point syllables through an independently authored curriculum, two guided practice modes, Free Type, and local-first progress tracking with optional cross-device sync.

Ownership and evidence
What I built
The product decisions and engineering work that shaped the final result.
Separated typing rules from the interface with a deterministic, framework-independent state machine for key matching, Shift handling, visual-order advancement, errors, timing, rhythm, and completion.
Modeled canonical Myanmar Unicode text, syllable segmentation, and physical KBDMYAN keystroke order as separate immutable views, including the front-vowel sequence where ေ is typed before its consonant.
Built a typed, six-track curriculum pipeline that derives the lesson catalogue, static practice routes, navigation, metadata, and sitemap from small reviewed content modules.
Designed an append-only IndexedDB progress log with runtime validation, anonymous and account-specific scopes, same-tab updates, cross-context refresh, and non-blocking writes.
Added optional Google sign-in and background cross-device history sync through Better Auth, Drizzle, and Neon Postgres; local completion is committed first, and network failure never blocks practice.
Created a fluid KBDMYAN keyboard with Shift and finger guidance, explicit Keys and natural Reader prompts, live WPM and accuracy feedback, Free Type sessions, four themes, bundled Myanmar fonts, and a bilingual learner guide.
Protected production routes with Content Security Policy, HSTS, restrictive permissions, cross-origin safeguards, clickjacking protection, and MIME-sniffing protection.
Enforced curriculum, Unicode, keyboard, and persistence invariants with Vitest, strict TypeScript, Biome, Lefthook, pinned GitHub Actions, and a reproducible pnpm workflow.
